If $$ I=\int \frac{\sin x+\sin ^3 x}{\cos 2 x} d x=P \cos x+Q \log \left|\frac{\sqrt{2} \cos x-1}{\sqrt{2} \cos x+1}\right| $$ (where $$c$$ is a constant of integration), then values of $$\mathrm{P}$$ and $$\mathrm{Q}$$ are respectively

$$\frac{1}{2}, \frac{3}{4 \sqrt{2}}$$

$$\frac{1}{2}, \frac{-3}{4 \sqrt{2}}$$

$$\frac{1}{2}, \frac{3}{2 \sqrt{2}}$$
